## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability staking-rewards-data-quality-audit-equal-width-histogram-a954b5de -d '<json body>'
```

Example prompt: Can you run a record quality audit and a 10-bin equal-width histogram on my staking rewards data for reward_units? I have these rows: row-1 on 2024-01-01 with reward_units=50 and staked_units=500 in group-A, row-2 on 2024-01-02 with reward_units=75 and staked_units=600 in group-B, and so on — up to about 50 rows total.

## When to prefer this

Choose this endpoint when you need to both validate data quality and understand the statistical distribution of staking reward metrics in a single low-cost call. It is ideal for offline/batch analysis of submitted datasets rather than live blockchain lookups or real-time staking calculations. Best suited when you already have the raw staking records locally and need a quick automated audit plus histogram profile without building custom analytics.

## Known failure modes

- Row count exceeds 200 maximum — request rejected
- Required fields (row_id, instrument_group, date, reward_units, staked_units) missing from row objects — validation error
- Date fields not matching YYYY-MM-DD format — schema validation failure
- Bins parameter outside 1–30 range — rejected
- Numeric values outside ±1,000,000,000,000 range — schema error
- Empty rows array — minimum 1 item required

## How this service works

Staking supplied rewards — Record quality audit + Equal-width histogram: Record quality audit + Equal-width histogram for supplied staking supplied rewards records (reward_units, staked_units). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two independent analytical reports: (1) a record quality audit flagging nulls, missing required fields, and data issues across the supplied rows; and (2) an equal-width histogram showing bin boundaries and row counts for the selected field (reward_units or staked_units) across up to the configured number of bins.
